Number 1: People losing their shit on their phones in public.

I just went out for a smoke and there was a bloke outside in a suit shouting into his phone and waving his free arm about wildly. As far as I could tell his main issue was that he was getting an unsatisfactory amount of respect from the person he was calling. His best line was "you don't want to come at me".

Eventually he realised he was looking like a twat so he put his non phone hand in his pocket. So then he looked like someone going into meltdown on his phone whilst also nonchalantly waiting for a bus.

Pretty much made my day this has.
